SPECIFICATION forming part of Letters Patent No. 76 ,313, dated July 5, 1904.

Applicrtion filed March 14, 1903.

To all whmn it Duty concern:

Be it known that 1, CHARLES W. STEVENS, a citizen of the United States, and a resident of the city of H arvcy, county of Cook, and State of Illinois,'havc invented certain new and useful Improvements in Building Construction; and I do hereby declare that the following is a full, clear, and exact description of the same,

1 reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. 7

This invention relates to a building construction, and more particularly to a wall construction in which the blocks of building ma terial are laid in courses. Heretofore ithas been customary in this class of construction to use mortar, concrete, cement, or the like in laying up the walls, and it requires a large expenditure of time and costly material, necessitating the use of skilled labor to do the work.

The object of this invention is to provide a construction obviating the requirement for skilled labor and by means of which a wall may be constructed with much greater rapidity than when mortar ,of any kind is used.

It is a further object of the invention to reduce the price of material while increasing the strength of the construction. This, considering the rapidity with which a wall may be laid,

reduces the cost to a minimum.

5 wall by means of ad The invention consists in the matters hereinafter described, and more fully pginted out and defined in the appended claims.

In the drawings, Figure 1 is aside elevation of a wall embodying my invention, showing the same in process of construction. Fig. 2 is a top plan view of the same. Fig. 3 is a section taken on line 3 3 of Fig. 1. Fig. is an enlarged fragmentary detail of the adhesive strips.

As shown in said drawings, a foundationwall A is provided of rubble or any desired material and leveled with a layer of mortar, cement, or the like a to receive the first course of the building-blocks B, which, as herein shown, are of molded artificial-stone construction. Said blocks age firmly unitedin the esive strips C, of felt,

paper, wood. or any suitable absorbent material, of sufficient thickness to form the desired thickness of joint and which have. been thoroughly impregnated wi h liquid cementing material. such as asphalt.- In laying up the wall'pieces c of the adhesive strip of a length approximately equal to the thickness of the blocks are placed vertically between the abutting ends thereof adjacent toeach side of the block. and when the course is laid lon- 6o gitudinal strips 0' of a length suflicient tooverlap several blocks are placed thereon adjacent to the edges- The pieces 0 and 0' are laid back a slight distance from the edges and sides of the blocks, so as to leave a space for pointing 5 the joints in the usual manner, thereby entirely inclosing the adhesive strips within the wall. Said strips may be of any desired width, but preferably as to leave a dead-air space between the same entirely around the block. If preferred, however, this space may be filled with asphalt or other cementing material.

The operation as follows: The strips, thoroughly impregnated and coated with the asphalt or the like, when placed in position form positive supports for the blocks and compress equally. The strips of course should be of sufiicient thickness toafiord room for pointing the joints when fully compressed. The as- O phalt adheres closely to the surfaces of the blocks and soon sets or hardens, forming a joint impervious to wind or water and of great strength and hardness and much more durable than ordinary mortar. 5

Obviously the details of arrangement and material of the strips may be varied and other cementing materials may be used than asphalt, and other details of construction may be varied without departing from the principles of my 9 invention.

I claim as my invention- 1. The combination with building-blocks laid in courses, of adhesivestrips. laid between and joining successive courses and the ends of a space between said strips.

2. In a' building construction the combination with building-blocks arranged in courses, of longitudinal, parallel adhesive 1 strips between the courses adjacent to each edge providing an inner inclosed space between the same.

3. In a wall the combination with courses of 5 building-blocks, of strips impregnated with asphalt engaged between the courses longitudinally thereof and adjacent to each edge, similar strips between the abutting ends of the blocks and a groove between the strips and 9 the side of the wall adapted to be pointed with mortar or the like, and a dead-air space being formed between said strips. 7 e In testimony whereof I have hereunto subscribed my name in thc presence of two subscribing witnesses.
